how do i control how much damage a projectile does to a destructable mesh

So in my game, i have a turret whose mesh is a destructable mesh. my player has two weapons, a rifle and a rocket launcher. the rocket launchers projectiles are also destructable meshes. I know how the whole accumulate damage thing works for DMs, and it does. My issue is that i want the rifle to take like 5 shots to destroy the turret, but i want the rocket launcher to destroy it in one shot. Is there any way i can make each projectile do a different amount of damage to the destructable mesh?
